Description

Technical Field

[0001] This utility model relates to the field of inverter technology, specifically to inverters and inverter heat dissipation structures. Background Technology

[0002] An inverter is a power electronic device mainly used to convert direct current (DC) to alternating current (AC). The output AC power can be used in various devices to meet the AC power needs of users in mobile power supply sites or areas without electricity. Its working principle is to use the switching characteristics of semiconductor devices (such as field-effect transistors, thyristors, IGBTs, or MOSFETs) to control the power supply voltage and current through rapid switching, thereby realizing the conversion of DC power into AC power of the corresponding frequency and voltage.

[0003] Inverters generate heat during operation, making heat dissipation a crucial aspect of inverter design. Existing inverter heat dissipation structures are not very effective and their cooling function is not stable. Over time, this can lead to damage to internal inverter components due to high temperatures. Furthermore, some existing inverter heat dissipation structures consume a significant amount of energy, and their energy consumption cannot be controlled, resulting in unnecessary waste and hindering practical use.

[0004] The prior art includes Chinese Patent Publication No. CN214900679U, which addresses the aforementioned technical problems. The technical solution disclosed in this patent document is as follows: an inverter heat dissipation structure, comprising a main body, a heat sink, and a heat sink mounting plate. This utility model overcomes the shortcomings of the prior art by incorporating a sensor, connecting rod, regulator, and indicator light. During use, the sensor operates, and when the internal temperature reaches a certain level, the indicator light illuminates, prompting the regulator to adjust the heat sink power. When the temperature is not excessively high, the regulator adjusts the heat sink power to minimize energy consumption, thus saving energy and improving practicality. However, in the above solution, the heat sink blades accumulate dust over time, reducing cooling efficiency. Therefore, regular disassembly and maintenance of the heat sink are necessary. Furthermore, the heat sink in this device is installed using multiple bolts, making disassembly and installation inconvenient and affecting work efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an inverter and an inverter heat dissipation structure to solve the problem that in the prior art, the fan blades of the heat sink will accumulate dust on their surface after long-term operation, and the accumulation of dust will reduce the cooling effect. Therefore, the heat sink needs to be disassembled and maintained regularly. However, the heat sink of this device is installed by multiple bolts, which is inconvenient to disassemble and install, affecting the work efficiency.

[0006] To solve the above technical problems, the utility model adopts the technical scheme that is:

[0007] The inverter heat dissipation structure, including inverter shell, the side of inverter shell is connected with the heat dissipation fan, both ends of heat dissipation fan are fixedly installed with mounting plate, the other side of every mounting plate is fixedly connected with the clamping plate, the other side surface of every clamping plate is attached with the iron sheet, the inside of every clamping plate is slidably installed with the clamping block through spring, and the inside of every clamping block extends the outside of every clamping plate and is mutually clamped with the inner wall of inverter shell, the side of every clamping block is fixedly installed with the connecting rod, and the inside of every connecting rod extends the inside of every clamping plate and mounting plate and is fixedly installed with the push piece.

[0008] The fan of the heat dissipation device is installed through a plurality of bolts, which is inconvenient to disassemble and assemble, and affects the work efficiency.

[0009] The utility model discloses a further improvement in the technical scheme that is: the side of inverter shell of every mounting plate bottom is fixedly installed with the connecting plate, the side of heat dissipation fan of every connecting plate bottom is fixedly connected with the reinforcing plate, and the top of every connecting plate is inserted with the insertion rod.

[0010] The utility model discloses a further improvement in the technical scheme that is: the inside of connecting plate of both ends of every insertion rod is attached with anti -skidding pad no.

[0011] The utility model discloses a further improvement in the technical scheme that is: the inside of connecting plate of both ends of every insertion rod is attached with anti -skidding pad no.

[0012] By adopting the above technical solution, the anti-slip pad can increase the friction between the surface of the connecting plate and the plug rod, reduce the possibility of the plug rod detaching from the inside of the connecting plate, and further improve the stability of the cooling fan installation.

[0013] A further improvement of this utility model is that: anti-slip pads are attached to the inside of the reinforcing plates at both ends of each insertion rod, each anti-slip pad is tightly attached to the surface of the insertion rod, and the top surface of each anti-slip pad has a slope that slopes inward towards the bottom.

[0014] By adopting the above technical solution, the friction between the surface of the reinforcing plate and the insertion rod can be increased by setting the anti-slip pad II, which reduces the possibility of the insertion rod detaching from the inside of the reinforcing plate and further improves the stability of the cooling fan installation.

[0015] A further improvement of this utility model is that: a magnet block is fixedly installed on the inner wall of the inverter housing on the other side of each iron sheet, and one side surface of each magnet block is attracted to the surface of each iron sheet.

[0016] By adopting the above technical solution, a magnetic block and an iron sheet are installed. Through the mutual attraction between the magnetic block and the iron sheet, after the card is inserted into the inside of the inverter housing, a certain attraction force can be formed between the iron sheet and the magnetic block. This reduces the possibility of the cooling fan detaching from the inside of the inverter housing from one side, further improving the stability of the cooling fan installation and the stability of the cooling fan in use.

[0017] A further improvement of this utility model is that each card block has an inclined surface on the other side that slopes outward.

[0018] The above technical solution involves creating a sloping surface on the card block. When the card block contacts the inverter housing, it can be placed inside the card plate without requiring operators to manually move the card block, thus improving work efficiency.

[0019] A further improvement of this utility model is that: each paddle's outer surface is provided with an inclined surface that slopes toward the inner end on the other side, and each inclined surface is covered with several anti-slip strips.

[0020] The above technical solution increases the friction between the operator's hand and the lever by setting anti-slip strips, reducing the possibility of slippage during lever operation, thus facilitating the disassembly of the cooling fan.

[0021] This utility model also provides an inverter, including any of the above-mentioned inverter heat dissipation structures.

[0022] Due to the adoption of the above technical scheme, the present application has the following technical progress compared with the prior art:

The inverter and the inverter heat dissipation structure, the magnet block and the iron sheet are arranged, after the clamping plate is clamped into the inside of the inverter shell, the iron sheet and the magnet block can form a certain adsorption force, thereby reducing the possibility of the heat dissipation fan being separated from the inside of the inverter shell on one side, further improving the stability of the heat dissipation fan installation, and improving the stability of the heat dissipation fan use.
